Transform positions

Transform positions command changes the positions of images in the image list by applying a transformation. You can apply a transformation from WGS84 coordinates to a projection system and/or a user-defined transformation.

The projection systems and transformations must be defined in the Coordinate transformations categories of TerraPhoto Settings.

To transform image list positions:

1. Select Transform positions command from the Images pulldown menu.

This opens the Transform image coordinates dialog:

transform_image_coordinates

2. Select settings and click OK.

This transforms the image positions for the active image list.

3. Save the image list using Save list or Save list As commands from the Images pulldown menu in order to save the changes into an image list file.

SETTING

EFFECT

Images to transform:

All images - all images in the image list.

Selected images - selected images only. This requires the selection of images in the image list before the command is started.

WGS84

Target projection system for applying a transformation from WGS84 coordinates to the given projection system. You can choose from any of the built-in or user-defined projections systems which are set as active in Coordinate transformations / Builtin projection systems, Coordinate transformations / US State Planes, and Coordinate transformations / User projection systems of TerraPhoto Settings.

Transform

User-defined transformation to apply. You can choose from any transformation that is defined in Coordinate transformations / Transformations of TerraPhoto Settings.

Dz

Value by which images are transformed in elevation. This is only active if Transform is set to Dz.

Dxyz

Location and name of a file that contains transformation values. This is only active if Transform is set to Dxyz.
